| 1 | Cold-chain transportation in the frozen food industry may have caused a recurrence of COVID-19 cases in destination:Successful isolation of SARS-CoV-2 virus from the imported frozen cod package surface显示文摘Coronavirus disease 2019(COVID-19)pandemic has spread in 220 countries/regions towreak havoc to human beings around theworld.At present,the second wave of COVID-19 has begun in many European countries.The complete control of COVID-19 is very urgent.Although China quickly brought the virus under control,there have been eight sporadic outbreaks in China since then.Both in Xinfadi of Beijing and Dalian outbreak of COVID-19,environmental swab samples related to imported cold chain food were tested nucleic acid positive for SARS-CoV-2.In this outbreak in Qingdao,we directly isolated SARS-CoV-2 from the cod outer package's surface swab samples.This is the first time worldwide,SARS-CoV-2 were isolated from the imported frozen cod outer package's surface,which showed that imported frozen food industry could import SARS-CoV-2 virus. | Peipei Liu Mengjie Yang Xiang Zhao Yuanyuan Guo Liang Wang Jing Zhang Wenwen Lei Weifang Han Fachun Jiang William J.Liu George F.Gao Guizhen Wu | 2020 | Biosafety and Health2020，2，4： | 41 |
| 2 | Utilization of polysaccharides as depressants for the flotation separation of copper/lead concentrate显示文摘The interaction mechanism between dextrin and minerals has been investigated through micro-flotation, adsorption density measurements, Fourier transform infrared ray (FTIR) spectroscopic studies and dissolution tests. Dextrin shows a good depressing action towards galena but not chalcopyrite. FTIR spectroscopic studies indicate that dextrin chemically adsorbed on galena surface in alkaline pH range. Dissolution tests confirm leaching action of metal ions from chalcopyrite and galena surfaces, and dextrin-lead ion interaction. Adsorption measurements present that the higher adsorption density of O-isopropyl-N-ethyl thionocarbamate (IPETC) onto chalcopyrite than that onto galena, and IPETC adsorbed on galena decrease with increasing dextrin concentrations in the presence of dextrin, attesting the flotation results. | Qin Wenqing Wei Qian Jiao Fen Yang Congren Liu Ruizeng Wang Peipei Ke Lifang | 2013 | International Journal of Mining Science and Technology2013，23，2： | 16 |
| 3 | Collagen-binding basic fibroblast growth factor improves functional remodeling of scarred endometrium in uterine infertile women: a pilot study显示文摘Intrauterine adhesion(IUA) is a common cause of uterine infertility and one of the most severe clinical features is endometrial fibrosis namely endometrial scarring for which there are few cures currently. Blocked angiogenesis is the main pathological change in the scarred endometrium. The fibroblast growth factor 2(b FGF), a member of FGF family, is usually applied to promote healing of refractory ulcer and contributes to angiogenesis of tissues. In this study, the sustained-release system of b FGF100 μg was administrated around scarred endometrium guiding by ultrasound every 4 weeks in 18 patients(2–4 times). Results showed that after treatment, the menstrual blood volume, endometrial thickness and the scarred endometrial area were improved.Histological study showed blood vessel density increased obviously. Three patients(3/18) achieved pregnancy over 20 gestational weeks. Therefore, administrating the b FGF surrounding scarred endometrium may provide a new therapeutic approach for the patients with endometrial fibrosis. | Peipei Jiang Xiaoqiu Tang Huiyan Wang Chenyan Dai Jing Su Hui Zhu Minmin Song Jingyu Liu Ziqing Nan Tong Ru Yaling Li Jingmei Wang Jun Yang Bing Chen Jianwu Dai Yali Hu | 2019 | Science China(Life Sciences)2019，62，12： | 16 |
| 4 | Prognostic implications of epidermal growth factor receptor variant Ⅲ expression and nuclear translocation in Chinese human gliomas显示文摘Objective: To determine the prognostic implications and clinical significance of epidermal growth factor receptor variant Ⅲ(EGFRvⅢ) expression and EGFRvⅢ nuclear translocation in Chinese human gliomas.Methods: We retrospectively examined EGFRvⅢ expression and EGFRvⅢ nuclear translocation using immunohistochemistry in specimens of 240 Chinese patients with glioma, including 84 World Health Organization(WHO) II gliomas, 84 WHO Ⅲ gliomas and 72 glioblastomas(WHO IV). Factors that correlated with EGFRvⅢ and EGFRvⅢ nuclear translocation expression were analyzed by the Chi-square test. Kaplan-Meier methodology and Cox regression were used for the survival analysis.Results: Log-rank tests showed that patient age, Karnofsky performance scale(KPS) score, tumor grade,EGFRvⅢ expression, EGFRvⅢ nuclear translocation, 1 p/19 q codeletion, isocitrate dehydrogenase(IDH)mutation, Ki-67 labeling index and O6-methylguanine-DNA methyltransferase(MGMT) status(P<0.05) were significantly correlated with overall survival(OS) time. Multivariate Cox regression analysis revealed that patient age, tumor grade, EGFRvⅢ nuclear translocation, 1 p/19 q codeletion, and IDH mutation(P<0.05) were significantly correlated with OS. Patients with a high level of EGFRvⅢ nuclear translocation(≥7%) had both significantly shorter OS [hazard ratio(HR): 1.920, 95% confidence interval(95% CI): 1.228-3.003, P=0.004] and progression-free survival(PFS) times(HR: 1.661, 95% CI: 1.116-2.471, P=0.012) than those with a low level of EGFRvⅢ nuclear translocation(<7%).Conclusions: A high level of EGFRvⅢ nuclear translocation in glioma is an independent factor indicating a poor prognosis, but EGFRvⅢ expression is not an independent clinical prognostic factor. The level of EGFRvⅢ nuclear translocation maybe a novel and crucial prognostic biomarker in glioma. | Kaiyuan Yang Xiaohui Ren Liyuan Tao Peipei Wang Haihui Jiang Li Shen Yiming Zhao Yong Cui Mingxiao Li Song Lin | 2019 | Chinese Journal of Cancer Research2019，31，1： | 8 |

| 6 | Influence of surface modification of SrFe12O19 particles with oleic acid on magnetic microsphere preparation显示文摘Oleic acid was used as surface modification agent to improve the hydrophobicity of magnetic strontium hexaferrite particles.The structure and properties of treated magnetic particles were characterized by scanning electronic microscopy(SEM),Fourier transform infrared spectra(FTIR),powder X-ray diffraction(XRD) and magnetic property measurement system(MPMS).The results show that oleic acid is chemically enwrapped on the surface of SrFe12O19 particles.Magnetic particles modified by oleic acid are highly dispersible and strongly responsive to magnetism but with slight decrease in saturated magnetization.The affinity between magnetic particles and monomers is improved by surface modification,resulting in increased particle incorporation in magnetic polymeric microspheres.The surface modification mechanism of magnetic particles by oleic acid is addressed in this work. | Sifang Kong Peipei Zhang Xiufang Wen Pihui Pi Jiang Cheng Zhuoru Yang Jing Hai | 2008 | Particuology2008，6，3： | 7 |

| 8 | Immunity-and-matrix-regulatory cells derived from human embryonic stem cells safely and effectively treat mouse lung injury and fibrosis显示文摘Lung injury and fibrosis represent the most significant outcomes of severe and acute lung disorders,including COVID-19.However,there are still no effective drugs to treat lung injury and fibrosis.In this study,we report the generation of clinical-grade human embryonic stem cells(hESCs)-derived immunity-and matrix-regulatory cells(IMRCs)produced under good manufacturing practice requirements,that can treat lung injury and fibrosis in vivo.We generate IMRCs by sequentially differentiating hESCs with serum-free reagents.IMRCs possess a unique gene expression profile distinct from that of umbilical cord mesenchymal stem cells(UCMSCs),such as higher expression levels of proliferative,immunomodulatory and anti-fibrotic genes.Moreover,intravenous delivery of IMRCs inhibits both pulmonary inflammation and fibrosis in mouse models of lung injury,and significantly improves the survival rate of the recipient mice in a dose-dependent manner,likely through paracrine regulatory mechanisms.IMRCs are superior to both primary UCMSCs and the FDA-approved drug pirfenidone,with an excellent efficacy and safety profile in mice and monkeys.In light of public health crises involving pneumonia,acute lung injury and acute respiratory distress syndrome,our findings suggest that IMRCs are ready for clinical trials on lung disorders. | Jun Wu Dingyun Song Zhongwen Li Baojie Guo Yani Xiao Wenjing Liu Lingmin Liang Chunjing Feng Tingting Gao Yanxia Chen Ying Li Zai Wang Jianyan Wen Shengnan Yang Peipei Liu Lei Wang Yukai Wang Liang Peng Glyn Nigel Stacey Zheng Hu Guihai Feng Wei Li Yan Huo Ronghua Jin Ng Shyh-Chang Qi Zhou Liu Wang Baoyang Hu Huaping Dai Jie Hao | 2020 | Cell Research2020，30，9： | 7 |
| 9 | A New Temperature Channel Selection Method Based on Singular Spectrum Analysis for Retrieving Atmospheric Temperature Profiles from FY-4A/GIIRS显示文摘Hyperspectral data have important research and application value in the fields of meteorology and remote sensing.With the goal of improving retrievals of atmospheric temperature profiles,this paper outlines a novel temperature channel selection method based on singular spectrum analysis(SSA)for the Geostationary Interferometric Infrared Sounder(GIIRS),which is the first infrared sounder operating in geostationary orbit.The method possesses not only the simplicity and rapidity of the principal component analysis method,but also the interpretability of the conventional channel selection method.The novel SSA method is used to decompose the GIIRS observed infrared brightness temperature spectrum(700-1130 cm-1),and the reconstructed grouped components can be obtained to reflect the energy variations in the temperature-sensitive waveband of the respective sequence.At 700-780 cm-1,the channels selected using our method perform better than IASI(Infrared Atmospheric Sounding Interferometer)and Cr IS(Cross-track Infrared Sounder)temperature channels when used as inputs to the neural network retrieval model. | Peipei YU Chunxiang SHI Ling YANG Shuai SHAN | 2020 | Advances in Atmospheric Sciences2020，37，7： | 5 |
| 10 | Generation and analysis of expressed sequence tags from the salt-tolerant eelgrass species, Zostera marina显示文摘Zostera marina, a monocotyledonous angiosperm, is one of the most important seagrass species. To investigate the salt-tolerance mechanism and discover salt-tolerant genes in Z. marina, a cDNA library was constructed. Single-pass sequencing of the 5'ends of 4 081 clones yielded 4 002 high quality expressed sequence tags (ESTs), which were assembled into 241 contigs and 1 673 singletons, representing 1 914 unigenes. The average length of the ESTs was 582 bp, with sizes ranging from 100-1 500 bp. Basic Local Alignment Search Tool (BLASTX) analysis revealed that 1 664 unigenes had significant homology to known genes in the National Center for Biotechnology Information (NCBI) non-redundant (nr) database (E-value 5-10). Among them, the two most abundant genes encoded metallothionein (157 ESTs) and chlorophyll a/b-binding protein (38 ESTs), accounting for 7.1% and 1.7% of the total ESTs, respectively. Using Kyoto Encyclopedia of Genes and Genomes (KEGG), 1 462 unigenes were assigned to 1 161 pathways (E-value 5-10). A total of 938 unigenes were assigned Gene Ontology (GO) terms based on the GO hierarchy analysis, and InterProScan searches recognized 1 003 InterPro families. Three genes for metallothionein in Z. marina that belonged to Class II was identified. Results of this study will improve understanding of the molecular mechanisms of saline tolerance in Z. marina. | KONG Fanna ZHOU Yang SUN Peipei LIU Limin MAO Yunxiang | 2013 | Acta Oceanologica Sinica2013，32，8： | 5 |

| 13 | Roles of low?density lipoproteinreceptor?related protein 1 in tumors显示文摘Low-density lipoprotein receptor-related protein 1(LRP1,also known as CD91),a multifunctional endocytic and cell signaling receptor,is widely expressed on the surface of multiple cell types such as hepatocytes,fibroblasts,neurons,astrocytes,macrophages,smooth muscle cells,and malignant cells.Emerging in vitro and in vivo evidence demonstrates that LRP1 is critically involved in many processes that drive tumorigenesis and tumor progression.For example,LRP1 not only promotes tumor cell migration and invasion by regulating matrix metalloproteinase(MMP)-2and MMP-9 expression and functions but also inhibits cell apoptosis by regulating the insulin receptor,the serine/threonine protein kinase signaling pathway,and the expression of Caspase-3.LRPI-mediated phosphorylation of the extracellular signal-regulated kinase pathway and c-jun N-terminal kinase are also involved in tumor cell proliferation and invasion.In addition,LRP1 has been shown to be down-regulated by microRNA-205 and methylation of LRP1CpG islands.Furthermore,a novel fusion gene,LRP1-SNRNP25,promotes osteosarcoma cell invasion and migration.Only by understanding the mechanisms of these effects can we develop novel diagnostic and therapeutic strategies for cancers mediated by LRP1. | Peipei Xing Zhichao Liao Zhiwu Ren Jun Zhao Fengju Song Guowen Wang Kexin Chen Jilong Yang | 2016 | Chinese Journal of Cancer2016，35，1： | 4 |
| 14 | Effects of Epidural Spinal Cord Stimulation and Treadmill Training on Locomotion Function and Ultrastructure of Spinal Cord Anterior Horn after Moderate Spinal Cord Injury in Rats显示文摘Objective:To investigate the effects of epidural spinal cord stimulation(ESCS) and treadmill training on the locomotion function and ultrastructure of spinal cord anterior horn after moderate spinal cord injury in rats.Method:Nine adult female Sprague-Dawley rats were randomly distributed into three groups:①spinal cord injury group(SI,n=3).②spinal cord injury plus ESCS group(SE,n=3).③spinal cord injury plus treadmill training group(TT,n=3).All rats received a moderate spinal cord injury surgery.Four weeks after surgery,rats in SE group received an electrode implantation procedure,with the electrode field covering spinal cord segments L2-S1.Four weeks after electrode implantation,rats received subthreshold ESCS for 30 min/d.Rats in TT group received 4cm/s treadmill training for 30min/d.Rats in SI group received no intervention,as a control group.All procedures in these three groups lasted four weeks.The open field Basso,Beattie and Bresnahan(BBB) scale was used before and after intervention to evaluate rats' hindlimb motor function.Result:After four weeks intervention,rats in TT group improved their open field locomotion scores to 20.In contrast,no significant improvement was observed in groups SI and SE.The morphology of synapses and neurons were similar regardless of whether rats had undergone ESCS,treadmill training or not.Conclusion:ESCS alone was not sufficient to improve the walking ability of spinal cord injured rats.ESCS or treadmill training alone might not contribute to the changes of ultrastructure in anterior horn of spinal cord that underlie the recovery of walking ability.Further research is needed to understand the contributions of combination of ESCS and treadmill training to the rehabilitation of spinal cord injured rats. | WANG Yizhao HUANG Xiaolin XU Jiang XU Tao FANG Zhengyu XU Qi TU Xikai YANG Peipei | 2009 | 中国康复医学杂志2009，24，6： | 4 |
| 15 | A novel PDZ domain-containing gene is essential for male sex differentiation and maintenance in yellow catfish(Pelteobagrus fulvidraco)显示文摘The sex-determining genes are found to be variable among different fish species. Yellow catfish(Pelteobagrus fulvidraco) is an important aquaculture fish species in China with XX/XY sex-determining type. Recently, YY super-male yellow catfish has been successfully produced by combining hormonalinduced sex reversal method with sex chromosome-linked markers. Here, we identified a novel PDZ domain-containing gene in yellow catfish designated as pfpdz1, in whose intron the sex-linked marker was located. The coding sequence of pfpdz1 in Y chromosome was identical to that in X chromosome except a missense SNP(A/T) that changes an amino acid(E8V) in the N-terminal region. Pfpdz1 displayed male-specific expression during sex differentiation. Overexpression of pfpdz1 using additive transgenesis induces XX ovary to differentiate into testis-like tissue, while the targeted inactivation of pfpdz1 in Y chromosome using CRISPR/Cas9-mediated mutagenesis triggers ovarian differentiation. Furthermore,we demonstrated that pfpdz1 initiates testicular differentiation through upregulating expression of amh, dmrt1 and sox9a1, as well as downregulating expression of cyp19a1, foxl2 and wnt4. Our data provide functional evidence that pfpdz1 is significant for male differentiation and maintenance in yellow catfish. | Cheng Dan Qiaohong Lin Gaorui Gong Tianyi Yang Shuting Xiong Yang Xiong Peipei Huang Jian-Fang Gui Jie Mei | 2018 | Science Bulletin2018，63，21： | 4 |
| 16 | Genomic characterizations of H4 subtype avian influenza viruses from live poultry markets in Sichuan province of China, 2014–2015显示文摘Dear Editor,Avian influenza viruses (AIVs) have posed a serious threat to poultry production and public health. To date, more than fourteen AIV subtypes that are able to infect human beings have been documented. Also, it is suggested that new subtypes may be reported in the future, owing to the migration of wild birds and live poultry transportation (Gao, 2018).Poultry may act as a potential incubator for novel subtypes of avian influenza virus (Bi et al., 2016a; Bi et al., 2016b; Liu et al., 2014a; Su et al., 2017). Up to date, the H7N9 AIV emerged in February 2013 has caused 1,567 human cases,with a fatality rate of 39.2%(http://gffzz36b398b81f8a4a4chqpv5oxqpkvkc6u0u.ffgz.tsg.suse.edu.cn/influenza/ | Chuansong Quan Ting Huang Xiuwei Chen Jie Zhang Qianli Wang Cheng Zhang Tiyan Zhang Lijun Zhou Liumei Shu Chunrong Long Lei Yang Xunbo Du Yingze Zhao Peipei Liu Hao Song Weifeng Shi Yuhai Bi Qiang Lv William J.Liu George F.Gao | 2018 | Science China(Life Sciences)2018，61，9： | 4 |
| 17 | Inhibiting Hv1 channel in peripheral sensory neurons attenuates chronic inflammatory pain and opioid side effects显示文摘Both opioids and nonsteroidal anti-inflammatory drugs(NSAIDS)produce deleterious side effects and fail to provide sustained relief in patients with chronic inflammatory pain.Peripheral neuroinflammation(PN)is critical for initiation and development of inflammatory pain.A better understanding of molecular mechanisms underlying PN would facilitate the discovery of new analgesic targets and the development of new therapeutics.Emerging evidence suggests that peripheral sensory neurons are not only responders to painful stimuli,but are also actively engaged in inflammation and immunity,whereas the intrinsic regulatory mechanism is poorly understood.Here we report the expression of proton-selective ion channel Hv1 in peripheral sensory neurons in rodents and humans,which was previously shown as selectively expressed in microglia in mammalian central nervous system.Neuronal Hv1 was up-regulated by PN or depolarizing stimulation,which in turn aggravates inflammation and nociception.Inhibiting neuronal Hv1 genetically or by a newly discovered selective inhibitor YHV98-4 reduced intracellular alkalization and ROS production in inflammatory pain,mitigated the imbalance in downstream SHP-1-pAKT signaling,and also diminished pro-inflammatory chemokine release to alleviate nociception and morphine-induced hyperalgesia and tolerance.Thus,our data reveal neuronal Hv1 as a novel target in analgesia strategy and managing opioids-related side effects. | Qiansen Zhang Yimin Ren Yiqing Mo Peipei Guo Ping Liao Yuncheng Luo Jie Mu Zhuo Chen Yang Zhang Ya Li Linghui Yang Daqing Liao Jie Fu Juwen Shen Wei Huang Xuewen Xu Yanyan Guo Lianghe Mei Yunxia Zuo Jin Liu Huaiyu Yang Ruotian Jiang | 2022 | Cell Research2022，32，5： | 3 |
| 18 | Genomic characterization of SARS-CoV-2 identified in a reemerging COVID-19 outbreak in Beijing's Xinfadi market in 2020显示文摘After 56 days without coronavirus disease 2019(COVID-19)cases,reemergent cases were reported in Beijing,China on June 11,2020.Here,we report the genetic characteristics of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)sequenced from the clinical specimens of 4 human cases and 2 environmental samples.The nucleotide similarity among six SARS-CoV-2 genomes ranged from 99.98%to 99.99%.Compared with the reference strain of SARS-CoV-2(GenBank No.NC_045512),all six genome sequences shared the same substitutions at nt241(C→T),nt3037(C→T),nt14408(C→T),nt23403(A→G),nt28881(G→A),nt28882(G→A),and nt28883(G→C),which are the characteristic nucleotide substitutions of L-lineage European branch I.This was also proved by themaximum likelihood phylogenetic tree based on the full-length genome of SARS-CoV-2.They also have a unique shared nucleotide substitution,nt6026(C→T),which is the characteristic nucleotide substitution of SARS-CoV-2 in Beijing's Xinfadi outbreak.It is noteworthy that there is an amino acid D614Gmutation caused by nt23403 substitution in all six genomes,which may enhance the virus's infectivity in humans and help it become the leading strain of the virus to spread around the world today.It is necessary to continuously monitor the genetic variation of SARS-CoV-2,focusing on the influence of key mutation sites of SARS-CoV-2 on viral transmission,clinical manifestations,severity,and course of disease. | Yong Zhang Yang Pan Xiang Zhao Weifeng Shi Zhixiao Chen Sheng Zhang Peipei Liu Jinbo Xiao Wenjie Tan Dayan Wang William J.Liu Wenbo Xu Quanyi Wang Guizhen Wu | 2020 | Biosafety and Health2020，2，4： | 3 |
| 19 | Personalized neoantigen pulsed dendritic cell vaccine for advanced lung cancer显示文摘Neoantigens are considered to be ultimate target of tumor immunotherapy due to their high tumor specificity and immunogenicity.Dendritic cell(DCs)vaccines based on neoantigens have exciting effects in treatment of some malignant tumors and are a promising therapeutic modality.Lung cancer is a lethal disease with the highest morbidity and mortality rate in the world.Despite the rapid development of targeted therapy and immune checkpoint inhibitors for lung cancer in recent years,their efficacy is still unsatisfactory overall.Therefore,there is an urgent unmet clinical need for lung cancer treatment.Here,we attempted to treat lung cancer using a personalized neoantigen peptide-pulsed autologous DC vaccine and conducted a single-arm,2 medical centers,pilot study initiated by the investigator(ChiCTR-ONC 16009100,NCT02956551).The patients enrolled were patients with heavily treated metastatic lung cancer.Candidate neoantigens were derived from whole-exome sequencing and RNA sequencing of fresh biopsy tissues as well as bioinformatics analysis.A total of 12 patients were enrolled in this study.A total of 85 vaccine treatments were administered with a median value of 5 doses/person(range:3-14 doses/person).In total,12-30 peptide-based neoantigens were selected for each patient.AIl treatment-related adverse events were grade 1-2 and there were no delays in dosing due to toxic effects.The objective effectiveness rate was 25%;the disease control rate was 75%;the median progression-free survival was 5.5 months and the median overall survival was 7.9 months.This study provides new evidence for neoantigen vaccine therapy and new therapeutic opportunities for lung cancer treatment. | Zhenyu Ding Qing Li Rui Zhang Li Xie Yang shu Song Gao Peipei Wang Xiaoqing Su Yun Qin Yuelan Wang Juemin Fang Zhongzheng Zhu Xuyang Xia Guochao Wei Hui Wang Hong Qian Xianling Guo Zhibo Gao Yu Wang Yuquan Wei Qing Xu Heng Xu Li Yang | 2021 | Signal Transduction and Targeted Therapy2021，6，2： | 3 |
| 20 | Ion exchange membranes from poly(2,6-dimethyl-1,4-phenylene oxide) and related applications显示文摘Ion exchange membranes(IEMs) play a significant role in fields of energy and environment, for instance fuel cells, diffusion dialysis, electrodialysis, etc. The limited choice of commercially available IEMs has produced a strong demand of fabricating IEMs with improved properties via facile synthetic strategies over the past two decades. Poly(phenylene oxide)(PPO) is considered as a promising polymeric material for constructing practical IEMs, due to its advantages of good physicochemical properties, low manufacturing cost and easy post functionalization. In this review, we present the accumulated efforts in synthetic strategies towards diverse types of PPO-based IEMs. Relation between polymer structures and the resulted features is discussed in detail. Besides, applying IEMs from PPO and its derivatives in fuel cell, diffusion dialysis and electrodialysis is summarized and commented. | Jiahui Zhou Peipei Zuo Yahua Liu Zhengjin Yang Tongwen Xu | 2018 | Science China Chemistry2018，61，9： | 3 |
